Whether glass in this group is mouthblown, machine drawn, or machine rolled, it is manufactured with the goal of making a glass that resembles "old window glass"... hence its classification as being "Restoration" glass. The mouthblown is the most "authentic", and the others are considered as more economic alternatives.

[NOTE: All stated dimensions of sheet glass are approximate. Because of the unique process and conditions of manufacturing art glass, the sheets are not perfectly square, nor are the sizes exact. Unless noted otherwise all sheet glass is approximately 1/8" thick.]
